Refrigerator

Abstract

A refrigerator includes: a heat-insulating main body composing a storage compartment; and a main door at an opening of the storage compartment, in which the main door includes: an opening provided at a front face of the main door; a sub door which freely opens and closes at the opening through rotation; an axis member for rotatably holding the sub door; a fixing member provided across a sub door side face and an opening inner side face, the sub door side face being a side face of the sub door in an axial direction of the axis member, and the opening inner side face being an inner side face of the opening opposite to the sub door side face; and a regulating member for regulating a rotational angle of the sub door at a predetermined angle by contacting the fixing member when the sub door is open.

1 . A refrigerator comprising:
 a heat-insulating main body composing a storage compartment having an opening at a front face; and   a main door which freely opens and closes at the opening of the storage compartment,   wherein said main door includes:
 an opening provided at a front face of said main door; 
 a sub door which freely opens and closes at the opening through rotation; 
 an axis member for rotatably holding said sub door; 
 a fixing member provided across a sub door side face and an opening inner side face, the sub door side face being a side face of said sub door in an axial direction of said axis member, and the opening inner side face being an inner side face of said opening opposite to the sub door side face; and 
 a regulating member for regulating a rotational angle of said sub door at a predetermined angle by contacting said fixing member when said sub door is open. 
   
     
     
         2 . The refrigerator according to  claim 1 ,
 wherein said fixing member protrudes from the sub door side face, and rotates along with the rotation of said sub door, and   said regulating member is provided at the opening inner side face.   
     
     
         3 . The refrigerator according to  claim 1 ,
 wherein said fixing member protrudes from the opening inner side face, and   said regulating member is provided at the sub door side face, and rotates along with the rotation of said sub door.   
     
     
         4 . The refrigerator according to  claim 1 ,
 wherein said main door further includes   
       a reinforcing member for suppressing a change in an attitude of said fixing member with respect to said axis member by holding said fixing member and said axis member. 
     
     
         5 . The refrigerator according to  claim 1 ,
 wherein said main door further includes a damper apparatus for suppressing a rotation speed of said sub door.   
     
     
         6 . The refrigerator according to  claim 1 ,
 wherein said main door further includes   an elastic member for biasing said axis member and said fixing member that are movable in the axial direction toward the opening inner side face or toward said sub door, and   said axis member and said fixing member are removed from said sub door or the opening inner side face by being moved against a biasing force of said elastic member.
